THE LOAD-DEFLEXION CHARACTERISTICS OF A DEEP RIGID ANCHOR IN AN ELASTIC MEDIUM

The axially symmetric problem of an infinite elastic solid containing a bonded symmetrically loaded spheroidal rigid inclusion is considered. This problem is of interest in connexion with the geotechnical study of the time-independent, load-deflexion characteristics of deep rigid anchors embedded in cohesive soil or rock media. The solution to the deep rigid anchor problem is obtained by making use of boussinesq's three-function approach applicable for the rotationally symmetric problem in the classical theory of elasticity. Load-deflexion relationships for rigid anchors of both prolate and oblate spheroidal shapes are presented in exact closed form. By treating the single anchor as a solid of revolution it is possible to investigate the influence of various geometric aspect ratios. From the exact load-displacement relationships presented here it is possible to recover solutions to anchors with spherical, circular or elongated shapes simply as limiting cases.(a) /TRRL/
